  Mac OS 10.4 Server.  I re-checked out the code today before sending  
an email just to be sure.

OH!!  It just hit me, for viewing the files I'm connected to the  
server through the Finder using Samba and these filenames have a  
colon in them.  A quick check on the command line verifies that the  
filename is indeed how you say it should be.  Sorry for the scare, I  
confused myself by accident.

However, the REPORT still fails with the above error although I have  
no problem seeing the collection and getting files through the  
browser (both GETs).

Since the filename is 007-04-11T10:52:00-0600_822729681.ics and the  
error refers to 2007-04-11T10%3A52%3A00-0600_822729681.ics, is there  
an escaping issue?

Thanks for the quick response,
